Air iscoinpressed within the lower end 16 of the cylinderl` and passes outthrough Asuitable .discharge ports and is conductedthrough piping 17 tothe air receiver and tanklS, which may be placed at any suitablelocation and ol a size adequate to the service and .type engine withwhich it vis being' used in conjunction. The inlet port 19 admits airfor conipres- .sion to the compression cylinderl. lhere it is'founddesirable to conserve'allv heat and prevent loss? thereof the piping 17and the tank may be A fuel supply tank 20, isdisposed .within the-pipingcircuitand is connected with the valve '24, by suitable pipingconnections as Pi-ping22 connects the air storage `tank 18 with thevalve 24.011 its one side terminating in an expansion nozzle within theprimary mixingivalve 24. A

n detailfof the valve is as shown in detail in y body *of passage of thefuel as A chamber23 is disposed within the the valve into which thepiping connection22 enters and 'the suction caused -througlifthe passageof the airvunder compression acrossthe chamber 23, causes a V gasolineorother fuel to enter-into the stream flow and to enrich Vthe saine.}The y'piping connection 23a enters Fig` 3.

y p tliecha'mber 23,0pposite the nozzle terminal Utilization and the airtanker receiver is between fifteen pounds minimum *and k'seventy-fivepounds maxiinum. .'VVhere liquid fuel is being used as the source ofenergy supply, the same is picked up ra'sa liquid and enters the chamber23,y as a liquid from, where the samenis mixed with the compressed air.and the same is volatilized." To further increase this volatol expandthe same into vapor, I pass the pipe 23a as'a coil 26 about s `theexhaust n'ianifold 25, of' the motor as v shown in Fig y This coilshould' bef'of substantial' lengtl'r to thoroughly heat`-tliepi-peJc'o'il 26, and to Vact as a storage supply lfor the mixedand'yaporized lfuel. A hood Y27v is disp'osediabout-Qthe-coil whichshould be covered with ,an insulating covering to conservethe-'heatimparted tothe coil from the exhaust manifold. The heated and mixed`fuel Vsupply is then conducted through pipe 28' andenters the throttleinlet valve 29,which is'shown in detail in Fig. 4, where- 'in 'a secondcompressed `mitted-totlne `chamber 30 disposed therein nec'te'dvdirectly with the posedv therein -inv advance `pipe 28 tojthe'valve29.AThe valve v29 conjair supply is ad- Which lis 'connected to supply pipey31 con- -air supply storage tank 18.v This'pipe Sl'has a valve 32 dis-yof the entry of the 'Beets4 the-fuel and air supply 'to the inletmanifold object of 'whichr insulated by any suitable meansV tov-preventthe free flow of heat therefrom.

21. I have found most economi-l cal results may be obtained wherein thecom-v pressionof the air disposed within 33 from where the mixed air andfuel enters the various cylinders of the prime mover. YDisposed withinthe chamber 30 of the inlet valve 29 is a throttle valve 311, the

is vto permit of manual manipulation of the valve and topa furthervmanual manipulation ofthe mixture of the air Vand fuel supply beingadmitted into the inlet manifold from where it is drawn into thecylinders for fuel.

'To facilitate the adjustment of the vgland nut 7, and to furtherprovide for the in`- spection and adjustment of other parts of the motorI have provided removable inspece tion plates 36, which are .disposedthrough the wall structure and which aresecured thereto by suitablefastening means.

Arsystem of this type may be connected to motors of the present type bythe use of an auxiliary air compressor to compress the air and a storagetank for storing the same for use in valves as herein outlined.

Applicant is aware that heretofore compressed air has been used toincrease the weight of the charge of fuel and to increase the poweroutput of the engine andf'therefore disclaims any bnt applicant isunaware that compressed an'v of a pressure of several atmospheres hasbeen.L used whilein a warmed state for the admixture of carboniferousfuel therein, then being` heated and the final admixture of compressedair before the entryv of the same into the cylinders-for power purposes.Applicant is further unaware that the cylinder of the prime mover hasbeen'used'as the compressor for the air to be used.
